Small Ti: Sapphire rod 3mm x 3mm x 2.5mm PL, I guess that would be Plano.
These are sealed never opened, one crystal per sale I have two available.
A customer asked if these were right angled or a Brewster's angle rhombus shape.
I had to open one to see and I have added photos of it's rhombus shape.
I combine ship as well.
